A Ministry of Justice spokesman said: "The re-release of life-licensed offenders is directed by the independent Parole Board once they are satisfied they can be safely managed in the community.

"Their life licence lasts for the rest of their lives, and they may be recalled to prison at any time for breaching their licence conditions. Additionally, they will be subject to strict controls and restrictions for as long as their risk requires them."

A spokesman for the Parole Board said: "We've had confirmation that all parties have been told and we can confirm that it was a release decision. He will be released."
